Lasmini is raped and thrown into a ravine, but is saved by Granny Lawu. She is then taught martial arts until the granny dies. Then Lasmini leaves the mountain to find her rapists and kills them one by one. One day, she has a fight with Mantili because she is close to Bentar. Then Lasmini returns to Mount Lawu to improve her martial arts. After learning new skills, she returns to challenge all the martial arts experts and is victorious. Mantili then goes to improve his skills from Brama and challenges Lasmini. Now Lasmini is defeated.
